Install

How do I install the io.usefulapi/deputy MCP server?

io.usefulapi/deputy is a hosted endpoint at https://deputy.usefulapi.io/mcp, so there is nothing to install locally. Ready-made configuration for Claude, Cursor, VS Code, Codex and 5 more is on this page, copied from each client's own documentation.

MCP tools · 21 exposed · ~3,270 tokens

The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →

Tool Tokens
deputy_add_unavailability ~166

Record a time an employee cannot work (one-off, or recurring with an RFC 5545-style rule such as FREQ WEEKLY, INTERVAL 1, BYDAY MO). Auto-scheduling then skips them. Deputy: POST /api/v1/supervise/unavail.

Common questions

What is the io.usefulapi/deputy MCP server?

io.usefulapi/deputy is an MCP server listed in the public MCP registry as io.usefulapi/deputy. See rosters, timesheets, leave and staff in Deputy, and create shifts, leave and memos. This page covers its hosted endpoint (https://deputy.usefulapi.io/mcp).

Is the io.usefulapi/deputy MCP server safe to use?

io.usefulapi/deputy scores 77 out of 100 on VerifyMCP. That is a record of what we were able to check automatically, not an endorsement. The category breakdown on this page shows every signal behind the number, including the ones we could not confirm.

What tools does the io.usefulapi/deputy MCP server expose?

io.usefulapi/deputy exposes 21 tools: deputy_whoami, deputy_list_locations, deputy_list_areas, deputy_list_employees, deputy_get_employee, and 16 more. Their descriptions and schemas cost roughly 3,270 tokens of context every time the server is loaded.

Does the io.usefulapi/deputy MCP server require authentication?

Yes. io.usefulapi/deputy asked us for credentials when we connected, so you will need to authorise it in your MCP client before it can do anything.

Is the io.usefulapi/deputy MCP server still maintained?

io.usefulapi/deputy is still listed as active in the MCP registry. We last reached this channel on 3 October 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.
